Sub-Miniature Latching Solenoid Valve

Sub-Miniature Latching Solenoid Valve

The new sub-miniature latching solenoid valve is specifically designed for applications that demand ultra-low power, low heat and small size. These features make the valve ideal for compact, battery powered pneumatic instruments such as portable oxygen delivery systems, environmental gas samplers, and other OEM flow switching devices. The new valve is magnetically latched and requires only momentary (10 ms) pulses of current to switch the state. It consumes only 2.8 milliwatt-sec per switch and has reliable bi-stable performance. Available in plug-in, face mount and ported soft tube configurations, the valve measures just 1.12" long x 0.28" diameter for compact manifold applications. The latching valve also features a flow capacity of 6 slpm at 10 psig and a pressure range of 0-15 psig.

High-Speed Solenoid Valves for Micro-Dispensing

High-Speed Solenoid Valves for Micro-Dispensing

Now available from Lee Products is the VHS micro-dispensing valve. This high-speed (1,200 Hz), two-way solenoid valve is designed for applications where size, dispense volume, repeatability and reliability are extremely important. The small size (0.22" diameter) allows placement of the valve directly over the individual well centers of standard 96 well micro-titre plates.

The VHS micro-dispensing valve is available with either a standard (0.05") or small (0.02") diameter outlet port or with an integral jeweled orifice for direct dispensing. The valve also features low power consumption (500 mW maximum) and a 200,000,000 cycle life. Wetted materials include stainless steel, PEEK, PPS and EPDM, ensuring a high level of chemical resistance and a wide range of fluid compatibility.

Lee HI-BAR Plug

Lee HI-BAR Plug

The Lee HI-BAR Plug is a reliable, leak-tight, threaded plug which has been designed to seal large passageways in hydraulic and fuel system manifolds. Rated for system pressures up to 5000 psi and temperatures from - 65 F to 275 F, Lee HI-BAR Plugs offer many advantages over existing threaded plug designs.

Significant savings are realised in reduced machining, assembly and inspection costs. A drilled and tapped hole is all that is required along with a simple installation tool. Installation is quick and easy and HI-BAR Plugs can be reused several times. The special features of the HI-BAR Plug are; simple installation hole, self-locking feature which eliminates lockwire, elimination of O rings due to the use of the Lee Multi Seal and aluminium and polyamide-imide materials for low weight.

A.F.O. Plug (Axial Force Only)

A.F.O. Plug (Axial Force Only)

The A.F.O. Plug provides a leak-tight, metal to metal seal in high pressure, high temperature manifold applications. Designed to be both removable and reusable, the plugs feature a floating seal that self-aligns to allow for threaded holes that are not concentric with the through hole. As a result of the plugs' two-piece construction, the seal does not rotate during installation, thus preventing galling of the seat. Also, since all the force is contained in the axial direction, the boss diameter can be smaller compared to other designs of plug.

Standard A.F.O. plugs are manufactured from corrosion resistant 303 and 15-5PH stainless steel and do not require O-rings or sealants. They are designed to withstand pressures up to 56,000 psi and temperatures to 600F, when fitted into hard materials and can be used in softer materials as well, such as aluminium or plastic.

The plugs are available in sizes from .190" to .750" with UNF threads, however, depending on specific application requirements, special versions can be supplied. A.F.O. plugs have recently been supplied in Monel in sizes up to 1,325" UNF threads to withstand 15,000 psi working pressure and 22,500 psi proof pressure.

A.F.O. Plugs are typically used in the offshore oil industry where applications include subsea wellhead trees, tubing hangers, completion tools, slick joints and down hole tools.

A range of NACE compliant A.F.O. Plugs made from MP35N is also available. These plugs conform to the requirements of NACE MRO175 / ISO 15156 and offer exceptional resistance to corrosion and sealing performance in high pressure, high temperature applications .

Semi-Inert Solenoid Valve

Semi-Inert Solenoid Valve 

The semi-inert LHIX Series solenoid valve is specifically designed to handle moderately aggressive liquids and gases in a wide range of fluid handling applications. The key features of these compact LHIX Series valves are light weight and low power consumption. This makes them ideal for use in inkjet printing, gas detection devices, anesthesia and reagent delivery systems, in addition to other similar OEM flow switching applications. Other features include enhanced elastomer inertness using (FFKM / PFE) elastomers and low internal volume.

The valves weigh less then 4.5 grams, measure just 1.12" OAL x 0.28" in diameter and operate with low power consumption of just 550 mW. Flow rates on gases for the 2 way option are; 11 LPM @ 10 psig and for 3 way; 6.6 LPM @ 10 psig. Latching and non-latching designs are available.

To ensure optimum design flexibility LHIX valves are available in plug-in, face mount and ported soft tube configurations. In addition to the FFKM and PFE elastomers, the wetted materials of the valves are; PPS (plunger head), PBT (housing), 316 CRES (spring), Epoxy, along with Lee's alloy for the armature and plunger stop which ensures superior corrosion resistance for more demanding.

A.F.O. Plug with an O Ring

A.F.O. Plug with an O Ring 

A new version of the AFO (Axial Force Only) plug has been designed to incorporate an O ring for additional sealing in specialised Oil Tool applications. The plug is designed to vent air from a product when filling it with hydraulic oil or to release trapped high pressure gas from an activated down-hole pyrotechnic tool when brought to the surface. Secondary retention of the plug in the manifold is provided by a circlip which prevents the plug from being removed completely from the manifold, thus safely protecting the operator during the gas venting process.

Hi-Bar Inlet Safety Screen

Hi-Bar Inlet Safety Screen

The Hi-Bar Inlet Safety Screen product line offers a new alternative for inlet filter screen design. Space and weight are minimised by incorporating the inlet screen into a fitting, rather than the more traditional approach of having the screen installed in the manifold directly below the fitting. This unique design also offers greater flow and dirt holding capacity than a design that completely encapsulates the screen in the fitting. The safety screens are machined entirely from 15-5PH and are available in -4, -6 and -8 configurations (AS33514 flareless tube to AS930 port fitting ends which can be installed into a standard boss per AS33649. Six standard hole sizes ranging from 0.003" (75 micron) to 0.020" (500 micron) diameter are available and the screens are rugged enough to withstand pressure differentials up to 6,000 psi without burst or collapse.
